I (naively) thought the last line can be somehow isolated in the engine so the
parfillskip settings doesn't influence the rest (too much).
I understand your point.

underful or overful where? in previous lines? I am quite lost here :-)

Wow, this is cool visualization!
When \zeropoint is replaced by e.g. 2em, I have what wanted originally.
Could anybody explain drawbacks of such approach? I mean especially that
overful magic above. I'd like to summarize this topic on Wiki.
